Summary

NAIP imagery may be distributed on an interim basis to meet USDA program requirements. The interim product is a compressed county mosaic. Users should be aware that the interim compressed county mosaic may contain defects and have horizontal accuracy less than the specified tolerances. Defective imagery may be replaced within one year of image acquisition date.

Description

This data set contains imagery from the National Agriculture Imagery Program (NAIP). NAIP acquires digital ortho imagery during the agricultural growing seasons in the continental U.S. A primary goal of the NAIP program is to enable availability of ortho imagery within one year of acquisition. NAIP provides two main products: 1 meter ground sample distance (GSD) ortho imagery rectified to a horizontal accuracy of within +/- 5 meters of reference digital ortho quarter quads (DOQQ's) from the National Digital Ortho Program (NDOP); and, 2 meter GSD ortho imagery rectified to within +/- 10 meters of reference DOQQs. The tiling format of NAIP imagery is based on a 3.75' x 3.75' quarter quadrangle with a 300 meter buffer on all four sides. NAIP quarter quads are formatted to the UTM coordinate system using NAD83. NAIP imagery may contain as much as 10% cloud cover per tile. The NAIP imagery here are provided via an OGC-compliant web mapping service (WMS) by the Maine Office of GIS and the Maine GeoLibrary Board.

Lineage 

Process step
When the process occurred 2007-01-04
Description Color Digital imagery was collected with a Leica ADS40 Digital Sensor. The ADS40 CCD array includes 12,000 pixels across track at 6.5 microns. The digital imagery was acquired with a minimum of 20% sidelap, then processed using Leica software to produce geo-referenced raster swaths. The ADS imagery is subsequently used in the Aerial Triangulation (AT) process in preparation for orthorectification. The horizontal accuracy of the orthorectified imagery is primarily determined by the quality of the airborne GPS, Inertial Measurement Unit (IMU) data and the surface model (digital elevation model or DEM). The AT process is initiated with the population of ADS project files with ABGPS/IMU data, horizontal control from USDA furnished mosaicked DOQQs (mDOQQs) and vertical control picked from the USGS DTED2 DEM data. IMU rotational data is checked by reading common points on the mosaicked DOQQs and on the new imagery. As a final check, stereo models are analyzed for parallax. The absolute orientations for each swath containing exterior orientation parameters for scan line is then output for use in orthorectification. Each DOQQ is inspected for relative horizontal accuracy with adjacent DOQQ tiles. Each DOQQ is inspected for image quality. DOQQs are color and radiometrically balanced over a block consisting of a large number of images. A sample of DOQQs is selected and inspected for relative horizontal accuracy with the USDA furnished mDOQQs. Completed and approved DOQQs are assembled into a countywide MrSID file, using a compression factor of 1:50.
